POLARIXPARTNER has had many interesting cases in recent years. Here are some of the most exciting cases, which reflect the full range of industries we support.

Value & cost management


Implementation of effective value and cost management for a new bus generation.


The goal of the project was to achieve cost savings of 20%, whereby the functionality should be increased (comfort, driving assistance, weight reduction, engine power, lighting). The total cost of ownership (TCO) should be improved by longer maintenance intervals, lower fuel consumption etc., always in compliance with public standards (for example, EURO 6).

POLARIXPARTNER executed the project over a period of three years, working hand in hand with more than 150 employees from the areas of R & D, Purchasing, CE, Controlling and Production.

Cost analysis of a slat transmission for a passenger aircraft


Cost analysis and implementation of cost savings of a slat transmission for a passenger aircraft of a Tier 1 aviation supplier.



The supplier had a strong production increase. However, some manufacturing steps are not compatible with mass production. The actual costs are higher than the target sales price. In addition, the customer increased the pressure to reduce costs because of the increase in the purchase quantity.

POLARIXPARTNER was commissioned with a 3-month analysis of the current situation. After 15 months, cost savings should be implemented. More than 50 employees from cross-functional teams including development, purchasing, cost engineering, controlling and production were involved.



  • Cost analysis of all parts and assembly
  • Workshops to identify cost saving oportunities (internally and with suppliers)
  • Evaluation of ideas in the team
  • Manufacturing analysis for in-house and supplier production in order to identify further potential
  • Production tests with new tools and processes to save on manufacturing costs
  • Negotiations with suppliers in order to unleash potential


  • 50 % Cost saving potential
  • 30 % of the potential already implemented after 6 months
  • Further measures to exploit the full potential over 9 months

Plant network optimization


LEAN project of a generic API manufacturer at about three different production sites of an international pharmaceutical company.


Competitors from China and India can offer 20-30% below their own price level in the market, which led to a decline in sales of 30%. The most important customer with the highest-margin product was about to change. Overall, there wasn’t an integrated operations management across the three production plants. Factory managers acted only locally.



  • Harmonization of targets across all levels of governance and alignment of targets for all production sites
  • Implementation of holistic planning and detailed planning systems in all production sites
